Tips. 1  Full-grown Chihuahuas generally don't get to be above 6 to 9 inches tall. 2  If yours is taller than that, either as a puppy or an adult, he may be a mixed breed. 3  Don't use color as an indication of your dog's breed, as both short-and long-haired Chihuahuas can come in practically any color.

Factors Affecting Wave Speed. The speed of any wave depends upon the properties of the medium through which the wave is traveling. Typically there are two essential types of properties that affect wave speed - inertial properties and elastic properties.
Wave Speed. A wave is defined as a disturbance which is moved medium; for example, the wave of the ocean moves in medium water and we can see the movement of wave crest from one side to the other side in a given time period. The motion of objects is described in terms of speed which shows the fastness of the object.. Group Velocity: It is the velocity with which the amplitude of the wave travels in the medium. It is given by the formula; $V_{G}$=$\frac{d\omega}{dk}$. So, it can also be defined as the rate of change of the angular frequency of the wave with respect to the angular wave number of the wave.
